As far as I know the only things gravity (spacetime curvature) and electrostatic force have in common is that the lines of force, when plotted as arrows, point inwards towards an electron or a negative charge, and inwards towards a massive gravitating body. Also, the force intensities decreases inversely proportional to the square of the distance.
In another way, a negative electrostatic charge carries a field analogous to that of a gravitating body; it attracts (its lines of force point inward analogous to that of a gravitational field).
Also note that a positive electrostatic charge has a repulsive field (its lines of force point in an outward direction). When both positive and negative charges are brought together they bind.
With the same logic that you describe, dipayankar, a positive electrostatic charge with a repulsive field is the same as a cosmological constant.
This is quite remarkable. But that does not mean they are one and the same thing. It could mean, e.g., that both phenomena are mediated by the same mechanism. There is certainly a connection.
